Congratulations, you now have a Message-Id: header :)
However, please look at
http://www.infradead.org/~dwmw2/message.jpeg
It shows your message still leaves a lot to be desired. Observe how
strangely you've quoted Nigel's message -- it appears as if you have
added the lines 'always add a message-id)', 'file.' and '-despite him
having' yourself, although in fact those are really part of the quote.
There's something _severely_ broken about your word-wrapping.
You also don't give any attribution to show whom you are quoting, Often
one can find this by looking at the To: header, but you didn't reply to
Nigel. Often one can find this by looking at the next message up in the
thread -- but your mailer omitted References: headers too so your reply
is artificially detached from Nigel's (which you can see at the top of
the index pane in the screenshot above).
The combination of these errors makes it really quite hard to interpret
your mail, in the general case.
